I have illustrated what I believe to be the V simplest embodiment of the invention where- V 10 in the interengagingportions of the protector side walls and theinsulating member are in thenatureof slots and extensions whilethe lens holding member or retainer is shown with a single ear or extension at each end,

I and the invention has been described in terms employed merely as terms of description and not as terms of limitation, but structural modifications are possible and may be'made V without, however, departing from the spirit of my invention. a a
